更新世的冰期-间冰期旋回导致了世界上几个地区物种分布范围的反复扩张和收缩。然而，尽管东亚生物群在全球生物多样性中的重要性得到广泛承认，但这种气候振荡是否对东亚生物群产生了类似的影响仍不确定。在这里，我们使用分子和生态位配置文件的11个东亚鸟类不同海拔范围，以揭示其对晚更新世气候变化的响应。生态位模型（ENM）一致表明，这些鸟类的范围可能会大幅收缩到南部的末次间冰期（LIG）和扩大其北方范围的边缘通过末次盛冰期（LGM），导致LGM范围观察到的所有11种。一致的是，基于25-30个核基因的聚结模拟在所有研究的物种中检索到了末次冰期显著人口增长的特征。气候统计数据表明，在LIG期间的高气候变化和LGM相对温和的气候可能解释了这些鸟类的历史种群动态。这是首次基于多个物种和两条生态位剖面和遗传数据来描述东亚生物群对晚更新世气候的独特响应的研究。本研究强调了在末次冰期气候变化的演变后果的区域差异，并意味着全球变暖可能会对该地区的物种构成很大的风险，在未来类似于LIG期间的潜在更高的气候变化。本文的在线版本（10.1186/s12862-017-1100-2）包含补充材料，可供授权用户使用。
The glacial-interglacial cycles in the Pleistocene caused repeated range expansion and contraction of species in several regions in the world. However, it remains uncertain whether such climate oscillations had similar impact on East Asian biota, despite its widely recognized importance in global biodiversity. Here we use both molecular and ecological niche profiles on 11 East Asian avian species with various elevational ranges to reveal their response to the late Pleistocene climate changes. The ecological niche models (ENM) consistently showed that these avian species might substantially contract their ranges to the south during the Last Interglacial period (LIG) and expanded their northern range margins through the Last Glacial Maximum (LGM), leading to the LGM ranges observed for all 11 species. Consistently, coalescent simulations based on 25–30 nuclear genes retrieved signatures of significant population growth through the last glacial period across all species studied. Climate statistics suggested that high climatic variability during the LIG and a relatively mild climate at the LGM potentially explained the historical population dynamics of these birds. This is the first study based on multiple species and both lines of ecological niche profiles and genetic data to characterize the unique response of East Asian biota to late Pleistocene climate. The present study highlights regional differences in the evolutionary consequence of climate change during the last glacial cycle and implies that global warming might pose a great risk to species in this region given potentially higher climatic variation in the future analogous to that during the LIG.
